1、Arduino程序的基本结构: //define variables before setup()voidsetup(){//将运行中不变的数值和属性固化到芯片中} voidloop(){//需要循环执行的代码} setup():setup()函数只运行一次,用来启动Arduino控制器,将运行中不改变的数值和属性固化到芯片中。The setup function runs once when you press reset or...

1、Arduino与电脑和蓝牙模块通讯都使用串口TX/RX,同时操作时产生冲突,程序写入Arduino时要断开与蓝牙相连的RX。 2、 执行时要注意,Serial.println()会将内容输出到蓝牙的另一端,而不是在电脑端显示信息。 3、蓝牙的默认密码是0000或1234。 4、如果外接驱动模块L298n时,需要将模块L298n和Arduino连接在同一电源上,...

2.使用说明使用时最需要注意的是,AD5252系列芯片需要在SDA和SCL上连接拉电阻才能正常通信。我用的测试电路图如下:SDA和SCL接Arduino uno的i2c接口,wp接13脚A0和A1,接对应的A0和A1脚。 3.编程指令首先设置ad5252的地址: AD0、AD1设置地址,高电平对应1。低对应于0。这两个引脚悬空时的默认地址是0x2D。写的...

See the description of digital pins for details on the functionality of the pins. As of Arduino 1.0.1, it is possible to enable the internal pullup resistors with the mode INPUT_PULLUP. Additionally, the INPUT mode explicitly disables the internal pullups. Syntax pinMode(pin, mode) ...
